The present disclosure generally relates to a methods, apparatus, and computer readable medium for implementing the methods for transmitting multi-bit SR (SRs) from a user equipment (UE). The UE may receive, from a base station, a radio resource control (RRC) message. The RRC message may indicate that uplink component carriers (CCs) of the UE are to be assigned to a plurality of uplink CC groups. Upon receipt of the RRC, the UE may assign the uplink CCs to the plurality of uplink CC groups. A multi-bit SR may be generated for each group of the plurality of uplink CC groups. The UE may transmit the multi-bit SR generated for each group of the plurality of uplink CC groups to the base station. Multi-bit SR transmission across different CCs may reduce latency in uplink grant and improve data transmission time.
